Bzzzzz! Wrong. :-) You can't make a XG-compatible MIDIfile on the EXR-5 using the built-in sequencer, but you can use the bankselect instructions according to XG-standard in for instance Cubase. The EXR-5 will playback such a file correctly, as if it were a Yamaha XG-device. Therefor you can make XG-files, using the EXR's capabilities to playback XG-files. That, and only that, is why Roland calls the EXR-5 "XG compatible".
Today I received an e-mail from Roland about this. They told me the "XG-voices" are in fact the normal Roland sounds, only assigned to program-change and bank-selects that follow the XG-standard.
